How To Use And Maintain Magnetic Reed Switches?

Don’t apply heat to the wire it will expand and shatter the glass. One way out is to hold the wire at the nearest point with a pair of needle-nose pliers so that heat sinks into the pliers for soldering.

Now ensure that the wire ends are the right distance apart so they fit in the sockets. You can use 2 pair of pliers to bend the wire ends that fit in the sockets, for safety so that the glass is not strained.

Advantages of Magnetic Glass Reed Switches

Generally, the advantage of magnetic reed switches is that the reeds are protected by atmospheric corrosion as they are placed inside evacuated glass capsules. Secondly flexibility is another factor that makes them popular. The reeds can be either of ferrous or non ferrous metals depending on the usage. They do not require standby power to operate when they are constructed in such a way to operate within a permanent magnetic field.

Disadvantages of Magnetic Reed Switches

One of the disadvantages of this type of switches is false signals are produced when subjected to heavy vibrations and fluctuating voltages. Heavy currents cause them loose springiness by overheating and make a few sparks fly. There is always the danger of damaging the glass for various reasons like handling and high voltages. This is because under high voltage they tend to get fused and “welded” permanently or if the weld is not strong enough, you can separate it by gently tapping the switch on the table. Any hard hitting would break the glass.

Waterproof Reed Switches

Waterproof reed switches are so flexible that they can be used even in damp and dirty places too. They are hermetically sealed and are totally waterproofed making them so versatile to use. They are available for matching actuating magnets.

Remote Contact Switches

Remote contact switches are very handy in car alarm systems. The remote (radio) control facilitates central locking function together with alarm. Additionally you can set contact switches for bonnet and boot it set of buzzer internally, which can replace the red light indicator.

Magnetic contact switch and magnetic alarm switch have revolutionized the way home or office security was being done. Though they need you to pay a little more attention they are worth the trouble.
