The handheld device improves an operability. The handheld deviceincludes a tabletprovided on the front side of the deviceand a grip partprovided on the backside of the deviceand to be griped by the operator H. The grip partis rotatable relative to the tablet

Handheld device and holder

The emergency stop switch unitas an operation switch unit includes a direct operation partA and an alternative operation partB. The direct operation partA has an emergency stop buttonadapted to be directly operated. The alternative operation partB is adapted to be linked with the direct operation partA and alternatively operates the emergency stop buttonin place of the direct operation partA. The alternative operation partB has a reception partthat detects a remote operation of the emergency stop buttonand an electromagnetic solenoidthat actuates the emergency stop buttonon the basis of the remote operation detected by the reception part

Operation switch unit, remote operation terminal and operation system

When an operator applies a removing force to turn a switch portion b in a direction Ca projection aabuts against a slope bso that the removing force as a reaction is applied to the slope. The removing force is divided into a component working along the slope band 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 bis moved downward as accordingly moving a movable contacts baway from a fixed contacts bvia a contact shaft b

Switch device

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.
