Abstract
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.
Claims19
A switch device, comprising:
- a first switch including a first blade and a second blade, wherein the first switch is configured to be opened or closed based on contact or non-contact between the first blade and the second blade;
- a second switch including a third blade and a fourth blade, wherein the second switch is 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, wherein the second blade is connected to a first conductor that passes through the housing, wherein the fourth blade is connected to a second conductor that passes through the housing, wherein both the first blade and the third blade are connected to a common conductor that passes through the housing, and wherein the first blade and the third blade are integrally coupled with each other to form a single integrated blade including the first blade and the third blade.
