Where are the mounting holes on limit switches?
Side Mounting Type Side mounting is usually associated with basic precision style limit switches. The switch body/receptacle is one piece and the wiring connections are made to either screw or solder terminals on the under-side of the switch. Mounting holes are provided through the side of the switch body. Special Purpose Limit Switches
How are mechanical limit switches used in industrial applications?
Mechanical limit switches are contact sensing devices widely used for detecting the presence or position of objects in industrial applications. The term limit switch is derived from the operation of the device it-self.
Which is the best material for limit switches?
Switch boxes Aluminum (die-cast) ADC Aluminum is often used as the material for the switch box (case) of Limit Switches. Standards are specified in JIS H5302. Zinc (die-cast) ZDC Die-cast zinc is more suitable than ADC for thin-walled objects, and its resistance to corrosion is also superior to ADC.
What are the contacts in a neutral position switch?
Neutral position switches have a double pole-double throw contact configuration. In this switch one set (pole) of contacts is actuated when the lever is actuated in one direction and the other set of contacts is actuated when the lever is actuated in the other direction. With this limit switch, direction of operation can be detected.
What kind of light does a limit switch use?
The indicating light allows the limit switch user to see at a glance what the status of the switch output is. The lights are usually either a 24-120 VAC/DC LED or a 120 VAC neon lamp. The load being switched should meet the voltage requirements of the light in order to insure the light functions.
Where does the actuation of a limit switch occur?
Actuation of the limit switch occurs only when the corresponding key is inserted into the key slot. The key is usually mounted on a door or machine guard in such a way that when door or guard is closed the key fits into the slot actuating the limit switch.
