20120228108 | Operation Switch - A push button switch | 09-13-2012 |
20120175228 | SAFETY SWITCH - A safety switch is improved by the feature of staying in an open position in the event of breakage of a working rod or breakage or dropout of an operation portion and having a simple structure facilitating size reduction. Even if a rotary shaft is released from a supported state in an operation portion because an operating force of an operation or the number of operations of extracting an actuator from the operation portion exceeds a breakage tolerance, a working rod is permitted to move in an urging direction of a coil spring and is assuredly moved to the operation portion. Therefore, a switch can be assuredly set to an open position and, hence, the safety switch can achieve the safety improvement. | 07-12-2012 |
20110002069 | ELECTRIC CIRCUIT - A functional element is prevented from breakdown and deterioration because of mounting and demounting of the functional element immediately after cut-off of driving power from a constant-current power supply or during supply of the driving power. | 01-06-2011 |
20100095719 | Door Lock Device With Safety Switch - A door lock apparatus with safety switch capable of assuredly locking a door is provided. | 04-22-2010 |
20100011818 | Safety switch - A safety switch is provided in which the open-close condition of a switching contact provided in a lock mechanism is reliably switched in a manner coupled with a motion of a lock member between a lock position and a unlock position. Since a link member, which directly and simultaneously switches the open-close conditions of normally-open and normally-closed switching contacts pursuant to the motion of a lock member, is provided, the open-close conditions of the normally-open and normally-close switching contacts can be switched reliably in a coupled manner with the motion of the lock member between the lock position and the unlock position. As a result, for example, by monitoring the open-close conditions of the normally-open and normally-close switching contacts, it is possible to determine to which of the lock position and the unlock position the lock member has moved, that is, which of the locked state and the unlocked state the rotation of the drive cam is in. | 01-21-2010 |
20090321227 | SAFETY HOLDER - A safety holder is provided that firmly attaches to a safety switch so that safety of a worker is enhanced. The safety holder includes a base body | 12-31-2009 |
20090205942 | Pushbutton Switch Device - Provided is a pushbutton switch device provided with a switch case in which a depressing member is arranged which, when moved downwards, depresses a switch. Arranged inside the switch case is an operating member which, when depressed, comes into contact with the depressing member to move the depressing member downwards. Provided in the peripheral edge of the operating member are a plurality of engagement portions to be engaged with the peripheral edge of the switch case. When the operating member is depressed, the depressed portion of the operating member rotates downwardly using, as a fulcrum, the engagement portion corresponding to the depressed portion of the operating member. | 08-20-2009 |
20090146506 | TWO-HAND SWITCH DEVICE - TaskāTo provide a two-hand switch device that requires only a small load for each operation cycle. | 06-11-2009 |
20080224878 | Relay - A light guide part ( | 09-18-2008 |
