摘要:
A double-throw switch comprises: a housing; a push button that is mounted for movement with respect to the housing; a first stationary terminal; a second stationary terminal; a moveable terminal that, when in contact with the first stationary terminal, closes a first circuit, and when in contact with the second stationary terminal, closes a second circuit; a first set of one or more positive stops that engage the first stationary terminal; and a second set of one or more positive stops that engage the second stationary terminal. The first set of one or more positive stops applies pressure to and maintains a predetermined position of the first stationary terminal. The second set of one or more positive stops applies pressure to and maintains a predetermined position of the second stationary terminal.

A case includes a housing, a cover and a switch module with a secure mechanism. The case has an accommodation portion. The cover is disposed on the case to have a cover position. The cover covers the accommodation portion. The switch module including a pressing switch and a switch-changing element is located in the accommodation portion and connected to the housing. The switch-changing includes a first pivot part, a pressing part, and a stop part. The first pivot part pivots the housing. The pressing part and the stop part jut from the first pivot part along different radial directions. The switch-changing element has a test position and a non-test position for rotating relative to the housing. When the switch-changing element locates at the test position, a position of the position of the stop part overlaps the cover position.

A normally-closed switch comprises: a housing; a push button that is mounted for movement with respect to the housing; a stationary terminal; a moveable terminal that, when in contact with the stationary terminal, completes a circuit; and one or more positive stops that engage the stationary terminal. When a force is applied to the push button, the moveable terminal breaks contact with the stationary terminal, thus opening the circuit. The one or more positive stops apply pressure to and maintain a predetermined position of the stationary terminal, but do not interfere with or impede the moveable terminal.
