    Can anyone tell me
    what is the low AC voltage (12V - 30 V) analogue of TRIAC (used at 220V AC)
    which can be used as a switch (having low resistance when switched ON) with a ON/OFF DC signal used for its switching.
    I can use relays (electromagnetic switch which can provides low resistance when switched on) but is there any other alternative from semiconductors devices which can work in the similar way as a triac or relay( it should provide low resistance when switched ON).

    Hi,

    Try something like a solid-state relay.

    A solid state relay. You can get ones that are activated by 3-32vdc or ones activated by line voltage.

    solid state relays are used for 115/220V AC (switched ON by 3- 32 V DC)
    I wanted to know the Semiconductor device which can be used for 10 - 30 V AC
    (activated by low DC/AC voltage)

    Hi,

    They are rated for 115 VAC, but they work fine for lower AC voltages. You can find them that use 10 VDC to switch.
