TYN612 THYRISTOR
- Thyristor is a switching device that can be used in power control circuit, over-voltage protection, and many other application. It requires a gate pulse to start, it gets self-latched and stays ON until the supply get interrupted. For this, we have to use a switching circuit in connection with the main supply of the circuit or across the thyristor to turn it OFF.
- Thyristor TYN612 is fit for all modes of control like overvoltage crowbar protection, motor control circuit, inrush current limiting circuits, capacitive discharge ignition and voltage regulation circuits.
- On-state RMS current is 12A
- Repetitive peak off-state voltage is 600V

REED SWITCH
- This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens. This makes for a great non-contact switch. This switch can carry up to 1.2A.
- 4*28mm Magnetic Reed Switch Sensor Normally Open
