Time delay relay with spring clips |
摘要 |
A time delay relay has a switch assembly, a spring terminal assembly, and an electrical resistance heater unit of an inexpensive construction held together in a reliable and economical manner by a pair of easily mounted metal spring clips. The clips have opposite ends each securely hooked over portions of the terminal assembly and resiliently engaged with respective, oppositely-facing surfaces of the switch and terminal assemblies so that the heater unit is firmly held in a predetermined position in the relay with opposite electrical poles of the unit resiliently engaged with respective terminals in the terminal assembly for directing electrical current through the heater, so that a thermally-responsive dished thermostatic disc is disposed in close heat-transfer relation to the heater unit at a location where it is free to move at a precisely predetermined temperature as it is heated by the heater unit, and so that a motion transfer pin is guided for free movement in response to the disc movement to provide snap-acting opening and closing of electrical contacts in the switch assembly.
