摘要：
An electrical switch comprises a housing with at least one fixed contact thereon and at least one resilient movable contact which has a fixed end secured on said housing and an opposite movable end with a contact portion which is held by the fixed end in a position spaced from the fixed contact. The housing includes a supporting member located between the movable and fixed ends of the movable contact and on the same side as the fixed contact. The movable contact is engageable by actuating means which includes a rotatable cam which first contacts an intermediate wave-shaped portion to cause an inwardly directed portion of the movable contact to move first into engagement with the support member and to subsequently cause the contact portion to move into engagement with the fixed contact.
