Circuit BreakersCircuit Breakers are devices used in place of a fuse to protect a circuit. There are manually resetable and au-tomatic reset types of circuit breakers. Manual reset breakers remain open on overload until the reset button isdepressed. Auto-reset breakers cycle or “continuously” reset until the overload is corrected. “Non-cycling” type IIcircuit breakers remainopenuntil overloadsituation is corrected.Powermust bedisconnected for breaker to reset.

Pressure Switches are used to cycle the A/C compressor or clutch either on or off, or both, (depending upon the design ofthe switch) when pressures in the A/C system either exceed or fall below the proper operating pressures. In some systems,pressure switches are also used to engage the engine cooling fan. There are two basic groups of pressure switches, thosenormally open, and those normally closed in their factory settings. Normally open switches disallow current flow within theirfactory setting range. Normally closed switches allow current flow within their factory setting range. Switches should bereplaced with the same type operation and pressure settings. Low pressure switches activate (open or close depending onwhether the switch is normally open or closed) on pressure drop. High pressure switches activate on pressure rise. Whilethe settings listed reflect factory settings, most switches will fluctuate + or - 3 to 10 p.s.i. A “quick find” chart is shown belowfor your convenience (does not include GM or Ford Accumulator, pressure cycling type).

Binary Switches perform two functions:A. Prevents compressor operation if system has refrigerant loss or ambient temp. drops too low.B. Prevents compressor operation if high side pressure rises too high. Automatically resets when pressure drops to normal.
Trinary II™ Switches are found on systems equipped with radiator shutters and/or electric or air fan clutches.They perform three functions:A. Prevents compressor operation if system has refrigerant loss, or ambient temp. drops too low.B. Prevents compressor operation if high side pressure rises too high. Automatically resets when pressure drops to normal.C. Overrides shutter/fan control to keep head pressure within normal range.

Section V: Illustrated Switches & Electrical Parts
RelaysRelays are basically remote control switches operated by an electro-magnetically produced force which opens or closes the relay’scontacts through which the main power current flows. (See Illustration A) Relays are normally used to provide minimum resistance onleads between a power source and consumer (motor, clutch coil, lamp, etc.). In order to keep resistance (which results in voltage drop) toa minimum, wire leads need to be as short as possbile and have a sufficient cross-section diameter/gauge size. The inclusion of a relaymeans that the power current can be routed directly from power source to consumer, and that the cable section can be correspondinglylarge. The weaker control current between the relay and control switch means that even small cable sections produce negligible voltagedrop (See Illustration B).There are 3 types of relays: normally open (N.O.), normally closed (N.C.), and the change-over type as shown below.Relays are available in 12 and 24v.
1. A normally open relay is used to close the electrical circuit between power source and consumer (the consumer is switched on).These type of relays are operated by means of switches, impulse generators, or control devices.
2. In practice, the normally closed function is performed by the change-over relay. A normally closed relay is used to break the circuitbetween power supply and consumer (the consumer is switched off). One application would be to use this type of relay in conjunction withstarting a vehicle to reduce load on the battery.
3. The change-over relay changes the current path from one electrical consumer to another. The relay is operated by a dash controlswitch. A typical application would be used in a compressor clutch/condenser fan circuit. Change-over relays can be used as normally open,normally closed, or change-over type relays.
Eliminating harmful voltage spikes can be accomplished by using relays supplied with resistors and diodes. Voltage spikesfrom 300v to 500v can momentarily occur when a relay is switched off. Sensitive electronic components can be damaged or malfunctionif these spikes reach the vehicle electrical network without suppression. A relay with a resistor (Illust. C) reduces these voltage spikesto less than 100v. A relay with a diode (Illust. D) eliminates them completely. The correct polarity of the connections to be made can befound on on the relay itself.
Truck Air Parts supplies relays for both OEM applications and add-on/universal type installations. When installing a universal or add-onrelay to an electrical circuit, always check the relay’s configuration beforehand to insure the proper relay is used for the application.

Superheat Switches (and thermal limiter fuses) are found on some earliermodel Chev/GMC trucks. These two components work in conjunction withone another. When the internal compressor temperature rises due to a lossof refrigerant or a restriction in the system, the superheat switch closes andallows current to travel to the thermal limiter fuse, melting the fuse, therebypreventing current from operating the compressor and clutch.

QUICK REFERENCE CHARTTHERMOSTAT SWITCH SPECIFICATIONS
The Thermostatic Switch controls the electrical circuit to the compressor clutch. Most thermostat switches havea capillary tube which is inserted into the fin area of the evaporator coil to sense its temperature. Matching boththe original location and the depth of the tube insertion during replacement is critical to obtaining correct systemperformance. Some thermostats are adjustable, others are fixed in their settings. In addition, some are solid statecontrols (Thermisters) and are used in conjunctionwith a probe to sense evaporator temperature. Excessive cyclingof the clutch, or no cycle at all, may indicate a malfunctioning thermostatic switch. All thermostatic switches listedclose at higher temperature and open at lower temperature.
