Description

本発明は、産業用機器の運転管理等に使用される、シリンダ錠とマイクロスイッチの組み合わせより成るキースイッチ装置に関するものである。   The present invention relates to a key switch device composed of a combination of a cylinder lock and a microswitch used for operation management of industrial equipment.

従来、鍵をロータに挿入してシリンダ錠本体を軸方向に押し込んでから特定方向に回す操作モードと、鍵をロータ７に挿入して、そのまま押込まずに特定方向と反対方向に回す操作モードという２つの操作モードを有するキースイッチ装置が提案されている(例えば特許文献１参照)。このキースイッチ装置は、各操作モードによって第１マイクロスイッチ、第２マイクロスイッチおよび第３マイクロスイッチのような複数のマイクロスイッチを選択的にオン又はオフ操作することができ、キースイッチ装置の適用形態の多様性が得られるものである。   Conventionally, an operation mode in which a key is inserted into the rotor and the cylinder lock body is pushed in the axial direction and then rotated in a specific direction, and an operation mode in which the key is inserted into the rotor 7 and rotated in the direction opposite to the specific direction without being pushed as it is. A key switch device having two operation modes has been proposed (see, for example, Patent Document 1). The key switch device can selectively turn on or off a plurality of micro switches such as the first micro switch, the second micro switch, and the third micro switch according to each operation mode. Diversity can be obtained.

上記従来のキースイッチ装置は、シリンダ錠本体を軸方向に押し込む操作を含めることにより、複数のマイクロスイッチを選択的にオン又はオフ操作するものであるが、シリンダ錠本体を軸方向に移動自在に支持する機構を組み込むことは、設置場所の条件によって困難である場合が多い。したがって、本発明は、鍵をシリンダ錠のロータに挿入して、そのまま回す操作により、複数のマイクロスイッチを選択的にオン又はオフ操作できるキースイッチ装置を提供することを目的としている。   The above-described conventional key switch device selectively turns on or off a plurality of micro switches by including an operation of pushing the cylinder lock body in the axial direction. However, the cylinder lock body can be moved in the axial direction. Incorporating a supporting mechanism is often difficult depending on the conditions of the installation site. Accordingly, an object of the present invention is to provide a key switch device that can selectively turn on or off a plurality of microswitches by inserting a key into a rotor of a cylinder lock and rotating it as it is.
