Electrical Symbol Category: Proximity Sensors. The reed switch is an electrical switch operated by an applied magnetic field. DXF, DWG and Visio formats available.
Electrostatic sensor symbol , Electrostatic sensor. Touch sensitive sensor, Mercury switch symbol , Mercury switch.
Detects the inclination or motion.
All are well-proven designs manufactured to our high standards.
The symbol shown here for the proximity switch is of the electronic variety, as indicated by the diamond- shaped box surrounding the switch. A non-electronic proximity switch would use the same . Permission (Reusing this file). Limit switches may be directly mechanically operated by the motion of the operating lever. The model BGU magnetic switches serve to detect the limits of filling levels in bypass level indicators.
Messages indicated by LEDs behind imprinted symbols. Membrane switch for doorbell feature. A magnetic card reader is used in conjunction with the HRC3. The magnetic systems are notable for their high degree of protection and compact design. They are therefore particularly suitable for areas where dirt and cleaning are major factors.
Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications. In one mechanism, two opposing coils with an over-center spring or permanent magnet hold the contacts in position after the coil is de-energized. Along with the mechanically operated limit switches , magnetic reed switches ( magnetically operated) have been constantly gaining increased importance.
