Abstract:
A variable resistance slide control employs a housing having a front wall and a side wall integral therewith. A dielectric base having a resistance element and a collector element mounted thereon is secured to the housing in spaced parallel relationship to the side wall. A contactor engaging the resistance and collector element is constrained to move with a slider projecting outwardly of the housing through an elongated slot defined by the front wall and the base. The slider comprises a U-shaped section bearing against and interfitting with the front wall, a contactor frame provided with a pair of runners engaging the side wall, and a tolerance compensator limiting lateral movement of the slider. A pair of terminals secure the resistance element to the base and a bowed portion integral with each of the terminals electrically engages the resistance element at the innermost portion of the terminals.
Abstract:
A combination electrical control having a variable resistor, a pull-push switch and an overload circuit breaker connected in tandem and having a common actuator shaft. The shaft may be rotated to alter the resistance of the variable resistor. The pull-push switch and the circuit breaker may be closed or reset when the shaft is pushed or pulled. The overload circuit breaker and the pull switch are connected in series so that the opening of either component breaks a circuit.
