A switch device and a cooking device having a switch device. The switch device may include a first switch configured to be opened or closed based on contact or non-contact between a first blade and a second blade; a second switch configured to be opened and closed based on contact or non-contact between a third blade and a fourth blade; a housing that accommodates the first switch and the second switch therein; and an actuator disposed in the housing and actuated to selectively open and close the first switch and the second switch.

A fire alarm testing device including an electrical-switch assembly, and internal circuitry. The electrical-switch assembly includes a face-plate with the face-plate including two screw-holes, a control knob, two voltage/resistor measuring points, a plurality of electrical contacts, and two mounting screws. The internal circuitry is mechanically and electrically coupleable to the face-plate, and electrically communicable with a fire alarm system. The control knob also includes four rotatable positions including normal, open, ground, and short such that the fire alarm system is testable by rotating the knob. The electrical-switch assembly is rated for 0-40 volts direct current and is rated up to 350 milliamps and is rated up to 3.5 continuous current-amps. Preferably, electrical-switch assembly is water resistant sealed from dust and debris. Protective caps or plugs are installed where required to prevent foreign objects into the device.

A battery switch including a housing having a removable side panel, a base, and two terminals located within the housing. Each terminal has a fixed end and a free end. Each terminal extends upwardly from the base. Each free end is positioned in a space between the base and the housing. Wherein the free ends of each of the terminals are accessible by removing the side panel.
