Radiomaster TX15 - replacement switches

Radiomaster TX15 - replacement switches are original replacement switch assemblies for Radiomaster TX15 and TX15 MAX transmitters. They are used to repair the transmitter when the original switches are damaged or worn out. Some variants also allow you to modify the controls on the transmitter shoulders. Each assembly is mounted on a PCB with a cable terminated with a connector, so it connects to the transmitter without soldering.

The SA+SB and SC+SD variants include two 3-position switches on a shared PCB. They replace the switches on the upper front edge of the transmitter: SA+SB on the left side, SC+SD on the right side.

The SE and SF variants are for the transmitter shoulders. From the factory, there are buttons: a latching SE button on the left and a momentary SF button on the right. The SE variant is a 2-position latching switch that stays in the selected position. The SF variant is a 2-position momentary switch that returns to its default position when released. These switches are sold separately for these positions.

The SE+SF variant includes two 3-position switches, each on its own PCB, along with nuts. Both shoulder positions can be converted to 3-position switches, giving the transmitter six full-featured switches on top. This is especially useful for iNav airplane pilots, who can use them for mode selection, beeper, or light control. After installation, SE and SF must be set as 3-position switches in EdgeTX (SYS → Hardware → Switches), otherwise the transmitter will display a warning when switched on.

We recommend replacement for technically skilled users, as the grips and rear cover of the transmitter need to be removed. We recommend removing the batteries before installation. The plastic frames for installing switches in place of the SE and SF buttons are not included; use those supplied with the transmitter. The package always contains only the assembly of the selected variant.
