A shorting (make-before-break) switch connects the new circuit before disconnecting the old one. A non-shorting (break-before-make) switch disconnects the current circuit before making the new connection.
Rotary Switches Component Intelligence
Precision multi-position switching for control and signal routing.
What are Rotary Switches components?
Rotary switches provide multi-position control by rotating a shaft to connect different contact circuits. Selection hinges on the number of positions, poles, contact ratings, and environmental sealing requirements for your specific control interface.
How to Choose Rotary Switches Components
Selecting the right rotary switch requires balancing mechanical durability with electrical load requirements.
Switching Configuration
Define the number of positions and poles (decks) required. Ensure the indexing angle matches your UI needs.
Contact Rating
Verify current and voltage ratings. Low-level signal switching requires gold-plated contacts to prevent oxidation.
Environmental Sealing
Select IP-rated or sealed housings if the switch will be exposed to dust, moisture, or chemical cleaning agents.
Mounting Style
Choose between PCB-mount for compact designs or panel-mount with bushing for rugged user interfaces.
Actuation Torque
Consider the tactile feel and torque; higher torque prevents accidental switching in high-vibration environments.
