# What is the difference between "SMD/SMT" and "Straight" about Mounting Direction?

I'm looking for a tactile switch for mounting on a PCB. I use Mouser to find them. https://www.mouser.jp/Electromechanical/Switches/Tactile-Switches/_/N-5g2m?P=1z0z7pt

In that page, there is Mounting Direction filter, and there are 3 options: Right Angle, SMD/SMT, and Straight.

I know the meaning of Right Angle, but I don't know the difference between SMD/SMT and Straight when I select SMD/SMT with Mounting Style filter.

I thought there are no differences in terms of the way to mount and actuator orientation, but actually, the number of search results are different.

What is the difference?

• Short answer: The database that the distributor uses to let you search for different types of parts often has errors, or confusing data. Trust only the datasheets from the manufacturers themselves. Jun 26, 2019 at 18:35
