The electrical switch includes two fixed contacts and a rotatable knife contact having a rotational axis and including at least one longitudinal pair of blades flexibly connected to each other. The two fixed contacts as well as the blades in the rotatable knife contact are of a first electrically conductive material composition. The first and the second fixed contact includes a first contact pin and outer ends in the blades in the rotatable knife contact includes a second contact pin. The first contact pin and the second contact pin are of a second electrically material composition, which is different from the first material composition. The first contact pin and the second contact pin pass over each other during a switching event.

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 rotary knob switch can include: a knob head; a fixing mount disposed below the knob head and configured to allow at least a portion of the bottom of the knob head to pass through it; cam located at the bottom of the fixing mount and to be mated with the bottom of the knob head, a side of the cam forming at least one protruding control curved surface; and a slider, said slider being coaxial with the cam, ramp with different heights being provided along edge of the slider, wherein, when the cam rotates, the control curved surface of the cam presses the ramp of the slider, such that the slider slides along axial direction towards the bottom of the rotary knob switch, the knob head comprises an indicator block, the lower part of the indicator block is provided with an axial light guide column.

Example motor assemblies for architectural coverings are described herein. An example motor assembly includes a motor, a first switch to trigger the motor to retract an architectural covering, a second switch to trigger the motor to extend the architectural covering, and an actuator positioned to activate the first switch when the actuator is rotated in a first direction and to activate the second switch when the actuator is rotated in a second direction. Also described herein are example lever actuators for motor assemblies of architectural coverings. An example lever actuator detaches from the motor assembly to prevent excess force on the motor assembly that could otherwise detrimentally affect the motor assembly.

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 the first blade and the second blade; a second switch configured to be opened and closed based on contact or non-contact between the third blade and the 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. The first switch and the second switch may be fixedly supported by a support structure disposed on a same plane as a mounting plane for the actuator and may be positioned in a single inner space.
