A safety switch device includes a first support member and a second support member which are formed so as to secure a mobile terminal, and a grip part to be grasped by an operator’s hand. The safety switch device includes an enable switch for transmitting a signal for permitting a robot to operate, and an emergency stop button for transmitting a signal for stopping the robot. The first support member and the second support member are formed so as to secure a plurality of types of mobile terminals having different sizes. The grip part is disposed at the center part of the shape of the back surface of the mobile terminal, which corresponds to the position of the center of gravity of the mobile terminal.

The present disclosure relates to a mechanical AND-gate logic system that may make use of a first and second lever arms, a first pivot linkage coupling the lever arms, an output member, and a second pivot linkage coupling the second lever arm to the output member. The first lever arm has first and second spaced apart ends for independently receiving separate logic level 1 or logic level 0 input signals thereon, and an output end spaced apart from the first and second input ends. The output end is disposed generally equidistant from the first and second spaced apart ends. The second lever arm has an input end and an output end and can move in both pivoting and translating movements. The first pivot linkage couples the output end of the first lever arm to the input end of the second lever arm such that both the input end and the output end of the second lever arm are able to either pivot and or to translate. The second lever arm is only able to translate and apply a logic 1 level input signal to the output member, to thus generate a logic 1 level output signal, when a logic level 1 input signal is applied simultaneously to both of the first and second input ends of the first lever arm.
