Mechanism and connections

Presented By- A.Rajib Kumar Gupta

• In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.

• Basically switches are classified into 4 types1. SPST2. SPDT3. DPST4. DPDT

1.SPST

2.SPDT

3.DPST

4.DPDT

-make a polarity reversal switch using

DPDT

OFF CONNECTION

ON CONNECTION

ON CONNECTION(OPPOSITE POLARITY)

-make a switch to give series and parallel power

supply using DPDT

PARALLEL POWER SUPPLY CONNECTION

SERIES POWER SUPPLY CONNECTION

Make a switch connection to operate a bot for right and left turn

RELAY

MECHANISM AND USES

A relay is an electrically operated switch.

BASIC OPERATION-

(DE-ENERGIZED OFF) (ENERGIZED ON)

(PRACTICAL RELAYS)

Controlling switches through relay

How will u check the pins of a relay?
