Abstract
A thermally actuatable electrical switch construction having a resilient contact member normally biased into electrical contact with a stationary contact member while a temperature sensitive member of the construction is in a solid condition and normally tending to spring out of contact with the stationary contact member by the natural bias of the resilient contact member when the temperature sensitive member is rendered non-solid by sensing a temperature above a predetermined temperature. The construction carries a guide member operatively associated with the resilient contact member to provide a guide for the resilient contact member that will substantially insure that the resilient contact member will move and be maintained out of contact with the stationary contact member after the temperature sensitive member has been rendered non-solid. The guide member comprises a spring engaging and acting on the resilient contact member to tend to pull the resilient contact member out of contact with the stationary contact member.
