FAQ - KHAN ELECTRONIC

Q:Are there any points of caution for when hand soldering a Tact Switch?

Avoid bringing the tip of the soldering iron into contact with resin parts and applying too much pressure to terminals as it could affect the performance of the switch.

Q:Can Tact Switch products be used in a held-down state?

We do not recommend operating them held-down.

Q:What are normally open and normally closed switches?

・Normally open (N/O)The switch is normally open (off) and closes (switches on) when operated.・Normally closed (N/C)The switch is normally closed (on) and opens (switches off) when operated.

Q:What is the contact resistance of a switch?

Contact resistance indicates the electrical resistance of the part of a contact that makes contact. It includes the electrical resistance of conductive parts of springs and terminals.

Q:What is Maximum operating voltage?

Maximum operating voltage is the maximum voltage that can be applied to the resistive element specified for the potentiometer.

Q:What is Rated power?

Rated power is the maximum electric power that can be applied continuously to a potentiometer.

Q:What is the withstand voltage (voltage proof) of a switch?

Withstand voltage (voltage proof) is the maximum voltage at which insulation will not break down when a high voltage is applied between open contacts, between terminals and control shaft (lever) or between terminals and switch body.

Q:What is the insulation resistance of a switch?

Insulation resistance indicates the resistance between open contacts, between terminals and control shaft (lever) or between terminals and switch body.

Q:What is Reflow soldering?

Reflow soldering is a soldering method for surface mounting of components that uses solder paste or cream instead of molten solder and involves heating the entire PC board and its components.

Q:What is Dip soldering?

Dip soldering is performed by passing the workpiece through flowing molten solder.

Q:What is hand (manual) soldering?

Hand (manual) soldering is performed manually using a soldering iron.

Q:What end products are connectors used in?

Connectors are used in products with limited board space, such as smartphones, wearable electronics and headsets.
