ELECTRICAL CONTACT UNIT FOR ATTACHMENT TO A CONT ACTOR OR OTHER ELECTROMAGNETICALLY OPERATED SWITCH

摘要

An electrical contact unit for attachment to an electromagnetically operated switch comprising a housing divided into two parts each having depending therefrom a leg with a hooked end for engagement of the contact unit with a complementary formation on the switch. The two housing parts are held together by resilient coupling means permitting partial separation of the housing parts against the resilience of the coupling means whereby the contact unit is snap-engageable with the complementary formation on the switch. The contact unit includes relatively movable contact members which are operated by an operating member which couples with an operating member in the switch.
