Abstract

A fastening device which permits snap-in assembly of a switch to a panel or receiving member includes a resilient latching member connected to the switch housing and adapted to engage a shoulder of the receiving member. A second resilient member serves to urge the resilient latching member into contact with the shoulder. In one embodiment of the invention, the switch housing is inserted into a receiving portion of a control panel and a connector carries at least one resilient latching member adapted to engage a shoulder on the receiving portion. In this embodiment, the connector and panel cooperate to retain the switch.

Claims

1. A fastening device for a switch housing comprising:

a receiving member comprising a cavity adapted to receive said switch housing, said cavity having a side wall forming a limiting surface for limiting lateral movement of said switch housing, and a rear wall perpendicular to said side wall, said side wall having a shoulder;

at least one resilient holding element, said resilient holding element including a portion adapted to engage said shoulder said resilient holding element urging said portion in a first direction into engagement with said shoulder;

means for connecting said resilient holding element to said switch housing; and

at least one resilient second element disposed between said switch housing and said rear wall for urging said housing away from said rear wall and thereby for urging said portion in a second direction into engagement with said shoulder, said second direction being substantially perpendicular to said first direction, wherein said resilient second element is integrally connected with said resilient holding element and said connecting means comprises a movable web connecting said resilient second element and said switch housing.

2. A fastening device according to claim 1, wherein said receiving member includes an opening for actuating said resilient holding element from outside said receiving member.

3. A fastening device according to claim 1, further comprising a release key connected to said resilient holding element.
