ABSTRACT:
A switch (10) includes a pair of fixed contacts (20,22) spaced apart from each other. The switch (10) also includes a contact member (40) including a resilient base (42) and a pair of contact arms (80,82) connected to and extending from the base in a direction toward the fixed contacts (20,22). The switch (10) also includes a manually engageable member (110) connected with the contact member (40) for, upon the application of a predetermined force to the manually engageable member, moving the contact arms (80,82) into electrical contact with the fixed contacts (20,22) to complete an electric circuit between the fixed contacts. The resilient base (42) of the contact member (40) yields upon the application of the predetermined force to the manually engageable member (110). The resilient base (42) moves the contact arms (50,52) out of electrical contact with the fixed contacts (20,22) upon removal of the predetermined force from the manually engageable member (110).
