An input device includes a first switch unit, a second switch unit, and a third switch unit that switch a combination of a first fixed contact and a second fixed contact, a combination of the second fixed contact and a third fixed contact, and a combination of the third fixed contact and a fourth fixed contact between a contact state and a separation state using a first movable contact, a second movable contact, and a third movable contact that move integrally.

Input device

A rotational angle detecting device includes a resistor of which one end is connected to the power source and the other end is grounded, a rotary potentiometer having two wipers which come into sliding contact with the surface of the resistor, a control unit which detects voltage applied to each of the wipers depending on the positions thereof upon the surface of the resistor, two resistors connected at one end to each of the two wipers, and switching means which switch the connection state between the other end of the two resistors and the power source under control of the control unit.

Rotational angle detecting device

A switch section includes a common terminal connected to a terminal at one end of each of a pair of motors, a first terminal connected to a terminal at the other end of one of the motors and a second terminal connected to a terminal at the other end of the other of the motors, and three-contact switches each including one common contact and two switching contacts. In the switch section two switches corresponding to one direction selected from the up and down directions form a switch group, at least one switch corresponding to the other direction selected from the up and down directions is provided, two switches corresponding to one direction selected from the left and right directions form a switch group, and at least one switch corresponding to the other direction selected from the left and right directions is provided.

Drive unit

Gaps that divide a conductive portion include an I-shaped gap that passes through the center of a fixed contact, and L-shaped gaps that are located on both sides of the I-shaped gap. Longitudinal gap of the L-shaped gaps extend beyond a virtual straight line A-A that passes through the center of the fixed contact and extend in the direction orthogonal to the I-shaped gap, and are connected to lateral gaps. The L-shaped gaps are arranged point-symmetrically about the center of the fixed contact.
