Abstract: The emergency stop switch unit 2 as an operation switch unit includes a direct operation part 20A and an alternative operation part 20B. The direct operation part 20A has an emergency stop button 21 adapted to be directly operated. The alternative operation part 20B is adapted to be linked with the direct operation part 20A and alternatively operates the emergency stop button 21 in place of the direct operation part 20A. The alternative operation part 20B has a reception part 32 that detects a remote operation of the emergency stop button 21 and an electromagnetic solenoid 3 that actuates the emergency stop button 21 on the basis of the remote operation detected by the reception part 32.

Abstract: The handheld device improves an operability. The handheld device 1 includes a tablet 2 provided on the front side of the device 1 and a grip part 3 provided on the backside of the device 1 and to be griped by the operator H. The grip part 3 is rotatable relative to the tablet 2.

Abstract: A lighting apparatus includes a laser lighting module, an LED lighting module, and a sensor module. The laser lighting module includes a base part, a laser diode mounted on a substrate fixed on the base part, a ceramic phosphor upon which a blue laser light from the laser diode is incident, and a lens for adjusting luminous intensity distribution of light emitted from the ceramic phosphor, and is mounted on a module mount part of a mount body part. The LED lighting module and the sensor module are also mounted on other module mount parts of the mount body part, respectively. Thus, by mounting various combinations of the laser lighting modules and the LED lighting modules on the mount body part provided with a plurality of module mount parts, it is possible to manufacture lighting apparatuses for various uses at low cost.

Abstract: When an operator applies a removing force to turn a switch portion b in a direction C2, a projection a4 abuts against a slope b71 so that the removing force as a reaction is applied to the slope. The removing force is divided into a component working along the slope b71 and a component F working in a same direction as a center axis X. Thus, the removing force is converted into a force F in the same direction as the center axis X. By means of the force F in the same direction as the center axis X, a pushbutton support b6 is moved downward as accordingly moving a movable contacts b9 away from a fixed contacts b12 via a contact shaft b5.

Abstract: A push-button switch provided with a hollow push button, a case supporting it, and a switching mechanism having a first contact disposed within the case and a second contact disposed opposite to the first contact, with one of its ends being inserted into a hole of the push button. Within a hole formed in an inserted section of the switching mechanism, a slide block is provided slidably in a direction crossing the direction in which the push button is pushed. A slope capable of engaging with a slope of the hole of the push button is formed on the slide block. A coil spring (return spring) for energizing a shaft of the switching mechanism so as to abut the push button is provided on the bottom of the case. This configuration enables the push button to take up a first OFF state, an ON state and a second OFF state in order of depression.
