A key mechanism including one or more butterfly hinges. Each butterfly hinge may include a double wing design operative to move between a depressed position and non-depressed position. Hinged coupling mechanisms couple respective arms of the wings together. Additionally or alternatively, a key mechanism can include one or more half-butterfly hinges. Each half-butterfly hinge includes a double wing design operative to move between a depressed position and non-depressed position. A hinged coupling mechanism couples one set of corresponding arms of the wings together, while the other set of corresponding arms are not coupled together.

Embodiments relate generally to systems and methods for preventing arcing within a snap action switch, particularly by removing a portion of a contact carrier attached to a stationary contact. A method of forming a contact for use in a snap action switch may comprise welding a contact onto a contact carrier; trimming at least one edge of the contact carrier proximate to the contact; and installing the contact carrier into a snap action switch housing. Trimming the at least one edge of the contact carrier may also comprise removing flash formed during the welding of the contact to the contact carrier.

Apparatus and associated methods relate to a cover assembly having a plurality of ribs integrally formed within an actuator body envelope to increase the resilience of the actuator body envelope against high-pressure water cleaning. In an illustrative example, the actuator body envelope defines an actuator body chamber while an actuator envelope integrally formed with the actuator body envelope defines an actuator chamber. The actuator chamber and the actuator body chamber may adapt to receive an actuator via an insertion aperture at a proximal end of the body envelope. In some implementations, the plurality of ribs may advantageously increase the service life of the cover assembly.
